From Candlemas

From the Presentation of the Lord, also called Candlemas. Here the priest is saying the Gloria (or the Collect, not sure when I took this). The Collect is a beautiful one:

Almighty ever-living God,
we humbly implore your majesty
that, just as your Only Begotten Son
was presented on this day in the Temple
in the substance of our flesh,
so, by your grace,
we may be presented to you with minds made pure.
